Full specifications

Performance

How much it lifts, how far it reaches, how precisely it repeats.

Payload Maximum mass the robot can carry at the wrist flange, including the gripper/tool. Higher means it can handle heavier parts.: 0.8 kg

2th pct in class
Reach Maximum horizontal distance from the base axis to the wrist — defines the size of the work area. Higher means a larger envelope.: 440 mm

0th pct in class
Repeatability How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.: 0.05 mm

11th pct in class
Axes (DOF) Number of independently driven joints / degrees of freedom. 6 is standard for articulated arms; 4 for SCARA/palletizers; 7 adds elbow redundancy.: 4

Motion range & speed

Per-axis travel limits and rotational speeds.

Max axis speed Highest rotational speed of the fastest joint. Higher helps short, fast moves.: 300 °/s

75th pct in class

Axis	Range	Max speed
J1	-160° to 160°	300 °/s
J2	-25° to 85°	300 °/s
J3	-25° to 105°	300 °/s
J4	-360° to 360°	300 °/s

Physical

Size, mass and how it mounts.

Robot weight Mass of the manipulator (arm) without controller. Lighter eases mounting and mobile use; heavier often means stiffer/higher payload.: 8 kg
Mounting Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).: tabletop, floor

Environment

Conditions it can operate in — dust, water, temperature, cleanliness.

IP rating (arm) Ingress protection of the body against dust/water (IEC 60529). First digit = dust, second = water. Higher resists harsher environments.: IP20

0th pct in class

Control & software

Programming, languages and ecosystem.

Programming How the robot is taught: pendant, hand-guiding (lead-through), block/flow-chart, scripting, offline simulation.: hand-guiding, graphical, script
Languages Native robot programming language(s) — e.g. KRL (KUKA), RAPID (ABB), URScript (UR), INFORM (Yaskawa).: Blockly, LUA, Python
Offline programming Whether programs can be built and validated offline in a digital twin before deployment.: Yes

Connectivity & I/O

Signals, fieldbuses and tooling interfaces.

Fieldbus Industrial networks supported for PLC/cell integration (PROFINET, EtherNet/IP, EtherCAT, Modbus TCP, CC-Link, etc.).: Modbus TCP, Modbus RTU, EtherNet/IP, PROFINET
Integrated vision Whether a camera / vision system is built into the robot or controller.: No
